code for a useless machine

==========================

The useless machine uses an Atmel AVR ATtiny25 and a servo.

The internal clock frequency of the ATtiny is set to 8 MHz. That means

one step/clock cycle lasts 0.125 ms. 160 steps result in a 20ms cycle and are

the value of OCR0A register in CTC-mode.
